· JVASP-155585· NbCr2B2

NbCr2B2 is a hard ceramic boride compound combining niobium, chromium, and boron—a research-phase material in the refractory boride family. While not yet widely commercialized, materials in this class are investigated for ultra-high-temperature structural applications and wear resistance where conventional alloys fail, such as in aerospace propulsion, extreme thermal environments, and hard coating systems.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
